Global Mixed-mode Technology G971M 4A Low Dropout Regulator with Enable Features General Description Adjustable Output Low to 0.8V The G971M is a high performance positive voltage Input Voltage as Low as 1.4V and VPP Voltage regulator designed for use in applications requiring 5V very low Input voltage and very low dropout voltage at 400mV Dropout 4A, VO 1.05V up to 4 amps. It operates with a V as low as 1.4V and IN Over Current and Over Temperature Protection VPP voltage 5V with output voltage programmable as Enable Pin low as 0.8V. The G971M features ultra low dropout, Low Reverse Leakage (Output to Input ) ideal for applications where V is very close to V . OUT IN Power SOP-8 (FD) Packages with Thermal Pad Additionally, the G971M has an enable pin to further 2% Output Voltage reduce power dissipation while shutdown. The G971M VO Power OK Signal provides excellent regulation over variations in line, VO Pull Low Resistance when Disable load and temperature. The G971M provides a power OK signal to indicate if the voltage level of VO reaches Applications 92% of its rating value. Motherboards The G971M is available in the power SOP-8 (FD) Peripheral Cards package. It is adjustable using external resistors.

Operating Conditions are conditions under which the device functions but the specifications might not be guaranteed. For guaranteed specifications and test conditions see the Electrical Characteristics. Note 2: The maximum power dissipation is a function of the maximum junction temperature, T total thermal resistance, Jmax , and ambient temperature T . The maximum allowable power dissipation at any ambient temperature is (T -T ) / JA A jmax A . If this dissipation is exceeded, the die temperature will rise above 150C and IC will go into thermal shutdown. JA Note3: Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible. Note4: The package is placed on a 2-layer PCB (1oz/1oz) with 3vias.Please refer to Demo Board Footprint section. Ver: 0.3 TEL: 886-3-5788833
